Pacific Ridge Announces Drilling Plans for the Kliyul and RDP Copper-Gold Projects

Vancouver, British Columbia--(Newsfile Corp. - July 16, 2026) - Pacific Ridge Exploration Ltd. (TSXV: PEX) (OTCQB: PEXZF) (FSE: PQW) ("Pacific Ridge" or the "Company") is pleased to announce exploration plans for its 100% owned Kliyul copper-gold project ("Kliyul") and RDP copper-gold project ("RDP"). Kliyul is located in the prolific Quesnel terrane; RDP is located 40 km west of Kliyul at the southern end of the Toodoggone Mining District, one of Canada's hottest exploration districts (See Figure 1).

Highlights

• Kliyul: The Kliyul Main Zone ("KMZ"), just one target area at Kliyul, hosts 2.42 billion pounds copper equivalent ("CuEq") (see Table 1) or 5.7 million ounces gold equivalent ("AuEq") (see Table 2) in the Inferred Mineral Resource category. 2025 drilling at KMZ intersected 289.0 m of 0.77% CuEq* (0.26% copper, 0.75 g/t gold, and 1.54 g/t silver) (see news release dated November 18, 2025). Pacific Ridge plans on drilling 2,500 m at Kliyul this year with a focus on the M39 target. M39 is a high priority target that has never been drill tested.

• RDP: 2025 drilling at the Day target, just one target area at RDP, returned one of B.C.'s best porphyry copper-gold intervals that year. Drill hole RDP-25-011 intersected 112.2m of 1.35% CuEq* (0.76% copper, 0.86 g/t gold, and 3.16 g/t silver) (see news release dated October 23, 2025). This year the Company will be targeting the interpreted porphyry centre at Day and further defining last year's western magnetic lobe discovery with a 3,000 m diamond drill program.

"We are mobilizing to site right now and I expect that drilling will be underway by the end of the month," said Blaine Monaghan, President & CEO of Pacific Ridge. "I'm very excited about this year's exploration programs at Kliyul and RDP as we are focused on high-impact discovery drilling."

Kliyul

Owned 100% by Pacific Ridge, Kliyul is over 90 km² in size and is located in the prolific Quesnel terrane close to existing infrastructure, approximately eight km to the Omineca resource road and a 230-kilovolt high-voltage power line. KMZ hosts 334.1 million tonnes ("Mt") grading 0.33% CuEq (0.15% copper, 0.26 g/t gold, and 0.95 g/t silver) (see Table 1) or 386 Mt grading 0.459 g/t AuEq (0.236 g/t gold, 0.142% copper, and 0.911 g/t silver) (see Table 2) in the Inferred Mineral Resource category and remains open for expansion.

Notes for Tables 1 and 2

1. The effective date of the Mineral Resource estimate is July 31, 2025.
2. The Mineral Resource was estimated using the Canadian Institute of Mining, Metallurgy and Petroleum(CIM), Definition Standards for Mineral Resources and Reserves, as prepared by the CIM Standing Committee and adopted by CIM Council.
3. There has been no metallurgical testing on Kliyul mineralization. The Company estimates copper recoveries (CuR) of 80%, gold recoveries (AuR) of 65%, and silver recoveries (AgR) of 65% based on the reported recoveries from Mount Milligan.
4. The mineral resource is constrained within a pit shell using metal recoveries of Cu 80%, Au 65% and Ag 65%, an exchange rate of 1.30 CAD:USD, mining cost of C$3.5/t, process cost of C$7.0/t, G&A costs of C$3.0/t, pit slopes of 45 degrees and metal prices of $Cu = US$4.60/lb, $Au = US$2,600/oz., Ag = US$30.00/oz. A fixed bulk density of 2.77 t/m3 was used for the estimation of tonnes.
5. CuEq = Cu% + (0.6697*Au g/t) + (0.0077*Ag g/t).
6. AuEq = Au + (1.4929 x Cu) + (0.0115 x Ag).
7. Factors: 22.0462 = Cu% to lbs per tonne, 0.032151 = Au g/t to troy oz per tonne, and 0.032151 = Ag g/t to troy oz per tonne.
8. The CIM definitions were followed for the classification of Inferred Mineral Resources. inferred blocks were assigned for blocks with one drill hole within 150 m.
9. Mineral Resources are not Mineral Reserves do not have demonstrated economic viability. There is no certainty that all or any part of the mineral resources will be converted into mineral reserves in the future. The MRE may be materially affected by considerations including, but not limited to, permitting, legal, sociopolitical, environmental issues, market conditions or other factors.
10. All figures are rounded to reflect the relative accuracy of the estimate. Totals may not sum due to rounding as required by reporting guidelines.
11. See "NI-43-101 Technical Report: Mineral Resource Estimate for the Kliyul Project, Omineca Mining Division, British Columbia "prepared by Susan Lomas., P.Geo., Lions Gate Consulting Inc., Dr. Bruce Davis, PhD, FAusIMM, and Dr. Ron Voordouw, PhD. P. Geo for Pacific Ridge Exploration Ltd. completed September 18, 2025.

A six-kilometre-long porphyry copper-gold trend, comprising favourable geology, geochemistry, alteration and geophysics, exists at Kliyul. High-priority drill targets outside of KMZ include M39, KCC and Klip (see Figures 2 and 3). However, this year's 2,500 m drill program will focus on the M39 target (see Figure 4), which has never been drill tested.

The M39 target area is associated with a one-km long copper and gold soil anomaly. The target hosts monzonite dykes, magnetite skarn, sodic alteration, and chalcopyrite mineralized quartz veins as well as two circular magnetic anomalies. Additional IP geophysics is also planned for M39.

Klip is a blind porphyry target centered on a large near surface magnetic anomaly. The Klip target is in the vicinity of a historical BC MINFILE occurrence (094D 185) that records a NE-striking shear zone within QSP-altered volcaniclastic rocks. A one metre chip sample taken across the shear zone in 1985 yielded 3.8 g/t gold and 5.3 g/t silver. The magnetic anomaly at Klip, which is similar to KMZ's magnetic signature, leads Pacific Ridge to believe that the drilling to date has only tested one part of the porphyry system and that most of the system remains hidden and untested to the north.

The KCC target is a geochemical, geological, and geophysical target at the north end of the fertile Kliyul Creek Intrusive Complex ("KCC"). Chalcopyrite-pyrite-quartz veins are found at surface, and the target also has a coincident IP-chargeability, resistivity, and magnetic anomaly.

The Klip, KCC and M39 targets are also associated with copper-gold skarn occurrences, which commonly occur as distal expressions of copper-gold porphyry mineralization and are considered vectors to underlying porphyry centers.

RDP

Owned 100% by Pacific Ridge, RDP is over 100 km² in size and is located in the Golden Horseshoe at the southern end of the Toodoggone district, one of Canada's hottest exploration districts. The 2025 drill program at Day, just one target area at RDP (see Figure 5), confirmed that the porphyry copper-gold-silver mineralization intersected in the eastern magnetic lobe is in an east-northeast-striking, steeply northward-dipping tabular body, and that the western magnetic lobe is also mineralized.

2026 exploration plans at RDP include a property-scale high-resolution magnetic survey and magnetic vector inversion modelling as well as property-scale airborne magnetotellurics to advance and identify other porphyry targets at RDP. Additional induced polarization surveys and ground magnetotellurics is planned to further refine drill targeting at Day. The 3,000 m drill program will focus on testing the interpreted porphyry center between the western and eastern lobes and more fully defining the 2025 western lobe discovery (see Figures 6 and 7).
